Boot Code
A.1
The Boot Sequencer has three functions:
Achieve GETH PHY functions by programming the GETH PHYs over the MII bus when the RCW
corresponds to the following: GE-enabled in RGMII configuration or TDM selected (instead of RGMII).
Temperature Sense polling is done over an I
When polling, other common I
I
There are two ways to activate Temperature Sense polling:
The FPGA RAM block, EBR, hold the Boot Sequencer code. The code is loaded from the FPGA internal
Flash during Power-ON and begins to run when triggered from the BCSR_main module.
The Boot Sequencer stops when the fetched command code is zero. See the BSA (Boot Sequencer
Assembler) file in Section A.2, Boot Sequencer Assembler File.. Commands are described in Table
2-11 on page 2-23. The compiler, using the Perl programming language, applies binary parsing to the
source code.

According to SDOS initialize :
GETH PHY is configured from RGMII to MSC815x Boot-over-Ethernet mode immediately following
ADS Power-on-Reset.
Isolates GETH PHY for TDM port testing.
Displays die temperature by polling the Temperature Sense.
Press the “SCROLL” push button twice to set the default mode; there will be no polling.
Clear the BCSR12.6 TSENSE bit.
